Abstract

Proses pembelahan kayu bakar secara manual oleh UMKM masih terkendala kelelahan fisik, produktivitas rendah, dan risiko kecelakaan kerja. Penelitian ini bertujuan untuk merancang bangun rangka horizontal mesin pembelah kayu menggunakan baja profil Kanal U (UNP 80) standar SNI dengan metode Research and Development (R&D) berorientasi sistematika perancangan VDI 2221. Rangka prototipe dibuat dengan dimensi 1100 × 350 × 350 mm menggunakan pengelasan SMAW (elektroda AWS E6013). Pengujian komprehensif meliputi uji beban statis, getaran dinamis, inspeksi visual las, dan uji fungsional pembelahan kayu. Hasil menunjukkan lendutan maksimum rangka pada beban tekan 50 kN hanya 0,72 mm (di bawah lendutan izin 3,05 mm). Getaran lateral maksimum pada 3600 rpm sebesar 0,65 mm tanpa pergeseran rangka. Analisis teoritis kekuatan bahan menghasilkan Safety Factor (SF) balok utama 10,78 dan sambungan las baji 2,08 (di atas batas izin >1,5). Uji coba pembelahan pada kayu Mangga, Mahoni, dan Jati berdiameter hingga 30 cm berhasil dilakukan dalam 1,8–5,8 detik tanpa deformasi rangka. Rangka horizontal ini aman dan layak digunakan.
